“Using the ball as a prop, or any object as a prop, whether that’s the goalpost or crossbar…will be a foul next season,” Blandino told Dan Patrick.

Using the ball as a prop was previously outlawed. However, Blandino explained that the dunk had been grandfathered in along with the Lambeau Leap.

Blandino did not explain why the NFL decided to make the change now. However, the move may be in reaction to a dunk last season by Jimmy Graham of the Saints that knocked a crossbar askew (see GIF below).

Coincidentally, this change will come in the first season after the retirement of Tony Gonzalez (above). Dunking the football was his signature touchdown celebration.
